ADM213EARS

Overview

The ADM213EARS is a robust RS-232 and V.28 interface device from the ADM2xxE family, operating from a single 5 V power supply. It features four drivers and five receivers with full-duplex communication capability at data rates up to 230 kbps. The component includes an internal charge pump requiring only four external 0.1 μF capacitors. It provides ±15 kV ESD protection on all I/O lines and complies with EMC directives. The SSOP-28 package supports operation within a temperature range of -40°C to +85°C.

Feature Summary

• Complies with EU EMC directive (89/336/EEC) for low emissions and high immunity
• Provides ±15 kV ESD protection on all I/O lines per IEC 1000-4-2 standards
• Features shutdown mode that disables the charge pump and transmitters while keeping two receivers active
• Includes enable control pins for tristating receiver outputs

Applications

• Laptop computers
• Notebook computers
• Printers
• Peripherals
• Modems

Procurement Notes

Verify the specific ordering suffix 'ARSZ' against the manufacturer's current documentation to confirm package type and compliance status. Ensure the design accounts for the active-low shutdown logic and the specific pinout of the SSOP-28 package. Cross-reference the datasheet revision to confirm electrical characteristics match the intended application requirements.

Selection Notes

Select this component when designing systems requiring high EMI/EMC immunity and robust ESD protection in harsh electrical environments. It serves as a plug-in upgrade for older MAX2xxE designs. Consider the unique shutdown behavior where receivers R4 and R5 remain active for peripheral monitoring. Verify compatibility with TTL/CMOS input levels and ensure adequate thermal management for the SSOP-28 package.

Part Context

The ADM213EARS belongs to the ADM2xxE family of RS-232 line drivers and receivers manufactured by Analog Devices. This family is designed for operation in electrically noisy environments and offers backward compatibility with earlier ADM2xx products. The 'E' designation indicates enhanced EMI/EMC compliance and ESD protection capabilities compared to standard versions.

Replacement Considerations

The datasheet identifies the ADM2xxE series as a plug-in upgrade for MAX2xxE devices. Designers should verify pin compatibility and electrical specifications before substituting other RS-232 transceivers. No specific alternative part numbers are confirmed in the provided documentation.
